Referri ljin d ieate ing cylindrical extension lying adjacent the fastening flange on which the actuating device, e. g., the control sleeve 2 can swing. In the interior of the pot-like casing 1 the valve 3 is arranged, which is penetrated by conduits 4, 5 (Fig.

The pressure fluid enters the casing 1 of the control device through the inlet conduit 6 and reaches, through the channel 5, a port 7 which conducts the pressure fluid to the driving motor (see Fig. 5) for the reciprocating motion of the machine tool.

At the same time the fluid situated in front of the piston of the driving motor flows through the connecting port 3 in the caing 1 of the control device through the conduit 4 to an exit conduit 9 and from there back to the pressure fluid container.

The valve 3 has rigidly connected with It a cylindrical extension of smaller diameter th an that of the part through which pass the conduits 4 and 5 and on which a vane 10 is fixed. The vane acts as a piston on being acted upon by the pressure-liquid and is able to oscillate with the valve 3 in an annular space 11 which is formed by the cylin drical part of the casing 1, on which the control sleeve 2 is arranged. The movement of vthe vane 10, and therefore ofthe valve 3,

is limited by a partition wall. 12.

A number of longitudinal channels are ar ranged in the control sleeve 2 which on a suitable movement of the control sleeve can be brought opposite corresponding openings in the casing 1 of the control device (Figs. 2 and 4).

The opening 13 of the openings referred to in the casing 1 is connected by a conduit 14 arranged in the casing, with the inlet conduit 6. A continuation 15 of the conduit 14 leads from the opening 13 to an openlng 16 in the casing 1.

A conduit 17 leads from the exit conduit 9 in the casing 1 to an opening 18 arranged in the casing.

According to the position of the control sleeve either, as with the position of the parts according to Figure 2, the channel 19 lies opposite the opening 13, or, if the control sleeve is correspondingly turned anti-clockwise, the channel 20 lies opposite to the opening 16,

Through the radial tapping 21 connecting with the channel 19, pressure fluid can reach,

as shown by the position of the control sleeve in Figure 2, a radial passage 22 in the cylindrical extension of the casing of the control device by way of 6, 14, 13, 19, and from there the pressure space 11 If the control sleeve is so turned that the channel 20 lies opposite the opening 16, then the pressure fluid can likewise reach the pressure space 11 by way of 6, 14, 15, 16, 20, through a radial tapping 23 out of the channel 20, and a radial passage 24 arranged in the cylindrical extension of the casing of the sleeve in Figure 2, an opening 25 leading direetly into the conduit 17 arranged in the casing 1. The annular space 11 is shown connected with the conduit 17 by the radial passage 26 of the cylindricalextension of the casing 1 and a radial tapping 27 and the opening 25 in the control sleeve.

In the position of the distributor sleeve represented in Figure 2, the pressure medium enters the annular space 11 through the ra dialpassage 22 and turns the valve 3 round anti-clockwise by acting on the vane 10 of the control motor. The pressure fluid lying in front of the vane 10 exits through the passage 26in the cylindrical extension of they If the control sleeve 2 is so turned anticlockwise so that the channel 20 comes opposite the opening 16 and the radial tapping 23opposite the radial passage 24, then a channel 28 arranged in the control sleeve 2 comes oppositethe opening 18. .From the chan: nel 28 there extends "a radial tapping 29, which then comes opposite a radial passage 30 in the cylindricalextension of the casing;

1, so that the annular space 11 is connected with the exit conduit 9 by the path 30, 29', 2s, 1s, 17.

Further channels 31, 32 are arranged in the control sleeve 2, which lead directly into the open. If the control sleeve 2 isrotated clockwise out of its position shown in Figure 2, then the channel 31 of the distributor sleeve leading to the open comes byway of a radial tapping 33 opposite a radial passage 34 in the cylindrical extension of the casing 1. Likewise by motion in the other direction the channel 32 leading tothe open is brought opposite a radial passage-36 in the cylindrical extension of the casing 1, by way of a radial tapping 35. I 1

A lever 37 is fastened on the control sleeve 2 and can be shifted from the position shown in full lines in Figure 2 into theposition shown in dot-and-dash lines and reversely by the projections 38, 39 on the reciprocated table 40 of the machine, e. g. the slide (see Fig. 5). g I

The operation of the distributor device is as fo1lows:-

through the inlet conduit 6 and by way of the conduit 5 in the valve member 3 and the connecting port 7 in the casing 1. From the berscarried'by the carriage and respectively adapted to coact with said lever upon engagement therewith at the end of the path of travel of said carriage to bring said conduits 3 into respective selected registry with each other to reverse the flow of said fluid driving medium 'wherebythe motor is reversed.

2. In a device-ofthe character described including in combination with a reversing It drive motorhaving a traveling carriage a control device comprising a casing having an extension, a sleeve member mounted for oscillation on saidflextension, said casing and sleeve member having respectively a pluralityof conduits for a fluiddriving medium, a valve member mounted for oscillation-with in said casing and having a plurality of conduits for a fluid driving medium, a vane typem'otor mounted for oscillation within 2d the extension of the casing and coaxially connected to said valve member, a lever carried byythe aforesaid sleeve member,stop members carried by the carriage and respectively adapted to coact with said lever upon engagement therewith at the end of the path oi travel of said carriage to bring said conduits intorespective selected registry with each other to reverse the flow ofsaid fluid driving medium whereby the motor is re- 30 versed, and conduits in said casing and sleeve members adaptedto vent said motor upon movement of the'sleeve member to a predetermined point beyond the end of the path over which it'is reciprocated by said stop members.

8. In a control device of the character described including incombinationwith areversing drive motor a control device comprising a casing having a' flange andan extension, a sleeve member mounted for oscillation on said casing, said casing and sleeve member having respectively a plurality of conduits for a driving mediuima valve mem-' ber mounted for oscillation within said cas-' verse the flow ofsaid fluid driving medium whereby the-motor is reversed, and conduits in said casing and sleeve members adapted to vent said motor upon movement of the sleeve member to a predetermined point beyond the end of the path over which it is recipro cated by said stopmembers. f In testimony whereof We afi'iX our signatures.
